Example: Gythja invokes Battle-blinder on a Lively unit of Bow-Drunes, making them unsighted. The Ysian player then activates the Bow-Drunes, Battle-blinder ends, and the Bow-Drunes, now Sighted, proceed to shoot the Gythja.
Hi Jereme
That's correct.
It's designed to make the unit in question easier to kill in combat (hence "battle-blinder") than just to make them blind. If they're unsighted, they fight poorly of course, because they can't see anything. So in a lot of ways it's aimed at warriors that are weary and about to be engaged, if that makes sense.
More playtesting is required to ensure that this spell is useful though - if people find it doesn't work well, I'll change it to "end of their next activation". That's a lot more powerful though, and price would increase.
Hope that helps.
